Abstract
The invention relates to a taper detection device which comprises a mandrel device, wherein one end of the mandrel of the mandrel device is fixedly provided with an end disk, and the other end of the mandrel can be slidably sheathed in a movable disk the diameter of which is greater than that of the end disk; the movable disk is fixed with the mandrel through top threads; and the end surfaces of both the end disk and the movable disk are perpendicular to the mandrel. When the taper detection device is used for measuring the taper of a taper hole, the difference between the large and small diameters of the taper hole is fixed, thereby greatly reducing the measuring parameters and enhancing the measuring accuracy. The taper detection device provided by the invention is simple in structure and convenient in operation.
Description
Technical field
The present invention relates to fields of measurement, be specifically related to a kind of tapering pick-up unit.
Background technology
In the check of mechanical component, often run into the detection problem of hole taper, traditional detection method is to measure outside diameter D, end diameter d, circular cone length L, utilizes formula C=(D-d)/L to calculate tapering C then.This kind method measurement parameter is more, and because the bus of cone is an angled straight lines, have bigger error when measuring outside diameter and end diameter, thereby the tapering precision that calculates is lower.
Summary of the invention
The purpose of this invention is to provide a kind of novel tapering pick-up unit, measurement parameter is few when using the present invention to measure the part hole taper, more convenient operation, and accuracy of detection is higher.
For achieving the above object, by the following technical solutions:
A kind of tapering pick-up unit, comprise a spindle unit, described spindle unit is that an end of axle is fixed with an end plate, and the other end is inserted in the Moving plate of a diameter greater than end plate slidably, described Moving plate is fixed by jackscrew and axle, and described end plate is all vertical with axle with the Moving plate end face.
Further, described Moving plate center hole wall and axle gap between 0.01-0.03mm, make Moving plate can along axle smoothly running fix can guarantee that again the card behind the Moving plate location is vertical with axle.
The end face of further described Moving plate and end plate and lateral vertical intersect, the measurement of the fixing and vernier height gauge of axle position when being beneficial to detect.
Beneficial effect of the present invention is, because the tapering of any one section cone equals the tapering of whole cone in the cone, this tapering pick-up unit is fixed as a constant value with the large and small end diameter difference in the tapering computing formula, promptly adopt the end plate and the Moving plate at axle two ends to realize, during measurement, the big end of workpiece taper hole is upwards lain in a horizontal plane on the testing platform, the related end plate of axle inserts the small end of taper hole vertically downward, then Moving plate is packed into along axle, use the dial gauge centering simultaneously, to guarantee the right alignment requirement of axle and workpiece taper hole, tighten jackscrew then.Big in the tapering computing formula thus, it is poor that the end diameter difference is fixed as the diameter of the Moving plate of this tapering pick-up unit and end plate card, all applicable in the taper measurement of different workpieces, the circular cone length L then is the vertical range between the card under card and the end plate under the Moving plate of the fixing back of the Moving plate of spindle unit, fixedly behind the Moving plate spindle unit is taken out when tightening jackscrew during practical operation, measure vertical range between two cards with vernier height gauge, both can obtain the circular cone length L, in this data substitution formula C=(D-d)/L, both can obtain the tapering of that section taper hole of surveying, also be the tapering of this workpiece taper hole.Adopt the present invention because the measurement parameter when having reduced actual measurement has greatly reduced measuring error, improved measuring accuracy, simultaneously simple in structure, convenient to operation.
Description of drawings
According to embodiment and accompanying drawing the present invention is described in further detail below.
Fig. 1 is the structure cut-open view that described a kind of tapering pick-up unit is implemented in invention.
Among the figure:
1, workpiece; 2, axle; 3, end plate; 4, Moving plate; 5, jackscrew.
Embodiment
Be illustrated in figure 1 as the structure cut-open view of a kind of tapering pick-up unit of the present invention, mainly comprise axle 2, end plate 3, Moving plate 4 and jackscrew 5, described end plate 3 places axle 2 one ends and fixes with axle, Moving plate 4 central hole, and the footpath of boring a hole is a bit larger tham the diameter of axle of axle 2, the other end that can be placed in axle 2 also can slide along axle 2, the taper hole that snaps in workpiece 1 when the Moving plate position determines that the back fixes Moving plate 4 and axle 2 with jackscrew 5, wherein end plate 3 all should be vertical with axle with the card of Moving plate 4, wherein the diameter of Moving plate 4 is greater than the diameter of end plate 3, specifically can produce different specifications according to the actual requirements, but for the ease of calculating, the diameter of end plate 3 and Moving plate 4 for integer, makes the big end diameter difference of taper hole be fixed as integer as far as possible.Improve the precision of measuring for trying one's best, reduce error, also strengthen the operability of this device simultaneously, the gap of Moving plate 4 center hole walls and axle 2 preferably remains between the 0.01-0.03mm, and Moving plate 4 is crossing with the end face and the lateral vertical of end plate 3.
Claims (3)
1. tapering pick-up unit, it is characterized in that, comprise a spindle unit, described spindle unit is that an end of axle is fixed with an end plate, the other end is inserted in the Moving plate of a diameter greater than end plate slidably, described Moving plate is fixed by jackscrew and axle, and described end plate is all vertical with axle with the Moving plate end face.
2. a kind of tapering pick-up unit according to claim 1 is characterized in that described Moving plate center hole wall and axle gap are between 0.01-0.03mm.
